Rename executables to avoid conflict with kraken

[yesimon]

When installing both krakenuniq and kraken (or kraken2) using conda, they both contain same-named executables such as classify and db_sort. Conda isn't aware of this conflict and overwrites these executables depending on which order the packages were installed. It would be great if this package can rename these dependent executables so there isn't any conflict. On the plus side, these dependent executables are not user-facing so it shouldn't affect user experience.

Hi Yesimon, indeed the conda recipe installs into the same directory and overwrites. I'll patch the conda build to install into a different directory.
